What is Sinon and how do I use it for testing?
An example of an AI chatbot conversation about Sinon, a JavaScript library for creating spies, mocks, and stubs.
What is Sinon and how do I use it for testing?
Sinon is a JavaScript library that provides standalone test spies, mocks, and stubs for your tests. It helps you create controlled environments for testing your code.
Can you give me an example of how to create a stub with Sinon?
Sure! You can create a stub like this: const myStub = sinon.stub(object, 'method');. This replaces the method with a stub that you can control.
How do I verify if a stub was called?
You can verify if a stub was called by using sinon.assert.called(myStub);. This will check if the stub was invoked during the test.
What are the differences between spies, mocks, and stubs?
Spies record function calls, mocks are pre-programmed with expectations, and stubs replace functions with controlled behavior.
